Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] Such as figure 1 As shown, the large-capacity completely passive containment cooling system provided by the present invention includes a plurality of storage tanks located above the containment for storing different coolants, namely A-type coolant storage tank 1 and B-type coolant storage tank 2 , Class C coolant storage tank 3. The system can use multiple coolants. According to the specific working conditions, the containment is sprayed with a single coolant or a combination of multiple coolants. The storage tanks 1, 2, and 3 are respectively connected to the generalized passive control unit GPCC5 through their respective coolant supply pipelines 4, and the generalized passive control unit GPCC5 is sprayed with the coolant located above the outer wall 11 of the containment vessel through the coolant spray pipeline 6. The device 9 is connected...

Abstract

The invention belongs to a containment cooling system, in particular, to a high-capacity and fully passive containment cooling system. The containment cooling system is used for collecting thermotechnical parameters related to the containment by using a sensor and tracking a cooling process; a plurality of storage boxes for storing different coolants is arranged above the containment; the dynamic control of containment cooling power can be realized by choosing the types of the coolants and adjusting the flows of the coolants; and by using a generalized passive control unit, the start-up and the whole running process of the containment cooling system can be completely independent on external power supply, thus the containment cooling system has a characteristic of fully passiveness.

Description

technical field [0001] The invention belongs to a reactor containment cooling system, in particular to a containment cooling system with large capacity, controllable cooling power, no external power supply for start-up and operation, and completely passive characteristics. Background technique [0002] The airtight containment is an important barrier to prevent the leakage of radioactive materials in the event of an accident in a nuclear power plant. The containment cooling system is used to ensure that the temperature and pressure of the environment inside the containment do not exceed the design allowable range, so as to maintain the sealing of the containment. AP1000 is a representative third-generation nuclear power system developed by Westinghouse Corporation of the United States. The final heat sink of the accident is acted by the atmosphere. Therefore, the containment of AP1000 should be used not only as an isolation boundary in case of an accident, but also as an int...
